ESP8266 Community Forum

- Tue Jun 05, 2018 1:37 pm #76301 Hello! I'm new with the esp8266 and I'm using Arduino IDE for the first time. I have some knowledge on microcontrollers using C.

I'm trying to make a network with a few ESP-12F. The idea is to control (activate a relay and get some data from a GPIO) each node individually from an android app through the internet. At first I want to control them with a web interface and leave the app for later.

I already been able to control one ESP-12F using an example that I found, in wich the ESP works as a web server and I had to use port forwarding and a DDNS. Now I was reading about different libraries (easyMesh, PainlessMesh, etc), but I'm a bit lost and don't know which one to use and how to do it. I want (if it's possible) each node to be able to connect to the router and with other node, so if one node gets down the network keeps working.

And I have some questions:
Will each node be working as a web server or I need to have one as web server and communicating to all the others?
Will each one have its own local IP and will I need to use port forwarding on each IP to have acces from an external connection?

I think thats all. Thaks in advance.

However, basically you said you want to control each node. So that means each node needs to be listening on the network for a command. So that means each node would be in server mode.

Hello and thaks for the answer.

Yes, that's what I want to do and I have just a basic knowledge in networks. I need to know if there is an Arduino library made for this kind of network (or another way to do it), because apparently easyMesh/PainlessMesh is not capable of create a mesh network that connects directly to a router.

In a few words I need to control each node from the internet.
